Abstract

The utility model relates to a fixed highway bridge basin-type rubber supporting seat, which is mainly composed of an upper seat plate, a bottom basin, a rubber plate, a sealing ring and a ground bolt, wherein, the upper seat plate is composed of an integrated top plate and a lower part lug boss. The bottom basin is composed of an integrated bottom plate and an upper circular ring. The four edges of the bottom plate are in the shape of a square, and the four edges are respectively tangental to an outer circle of the upper circular ring. The rubber plate is arranged in the inner hole of the upper circular ring of the bottom basin, and the sealing ring is embedded in the edges of a circular concave ring arranged on the top surface. The utility model has the advantages of compact structure and high loading capacity. The utility model can meet the need of bridge construction with different tonnages and different spans.

Description

Machine-made highway bridge pot rubber bearing

The utility model relates to the highway bridge member, and concrete is a kind of machine-made highway bridge pot rubber bearing.

Communications and transportation plays crucial effects in development of the national economy development, it is mainstay of the national economy industry, highway transportation is the chief component of communications and transportation, highway construction be unable to do without bridge construction, in the highway bridge structure, bridge beam body and bridge pier, be equiped with pot rubber bearing between the platform to solve Load Transfer and beam-ends corner problem, the pot rubber bearing of traditional structure uses for many years along practising, the prior art structural volume is bigger, supporting capacity is lower, bearing allows corner, displacement is all less, the demand of the highway bridge construction that incompatibility is growing is necessary its structure is improved, perfect, improve its performance.

Order of the present utility model provides a kind of improved machine-made highway bridge pot rubber bearing, makes its compact conformation, improves supporting capacity, satisfies the needs that different tonnages and span bridge are sent out construction.

The purpose of this utility model is achieved in that

A kind of machine-made highway bridge pot rubber bearing mainly is made up of upper base plate, end basin, rubber tile, sealing ring and stone bolt, it is characterized in that:

Upper base plate is made up of the top board and the lower boss of disjunctor, and top board is rectangular, its bottom surface has cylindrical boss, and this boss cylindrical has annular groove;

End basin is made of the base plate and the epirelief annulus of disjunctor, this bulge loop middle part is for there being end circular hole, these base plate four limits are square and four limits, and each is tangent and present down square shape of circle with the cylindrical of epirelief annulus, and the installing hole of an installation stone bolt is respectively arranged on the plane between four jiaos of this base plates and the last convex ring edge;

Rubber tile is a circular slab, is contained in the having in the end endoporus of epirelief annulus of end basin, and the end face of this rubber tile has circular recessed ring limit, is embedded with sealing ring in this recessed ring limit, and the sealing circle becomes tight fit with end basin endoporus and rubber tile is sealed in the end basin.

Described stone bolt passes the base plate of end basin, is connected in the reeded foundation of a cylindrical with bolt, is lined with the natural rubber packing ring of thickness 〉=2MM between foundation and base plate, and the construction preformed hole of the diameter of this foundation and length and bridge pier is corresponding.

The utility model has following actively useful effect:

1. volume compact.

2. the bearing supporting capacity is extended to .8MN-60MN by original 1000kN-20000kN, allows overload to be extended to 10% by former 5%.

3. enlarged the bearing corner, be extended to 0.02rad (1 ° 08 ') by original 0.01164rad (40 ').

4. this product can be designed to supporting series of products, and the bridge that satisfies different tonnages and different spans uses.
